There are 10 DSLAMs;
Neccessary to migrate to MPLS network;
Each DSLAM connected through 802.1Q trunk to the one PPPoE terminator, there are many vlan subinterfaces with PPPoE enable on.
The question: how to tunnel the each DSLAM trunk to one trunk connected to PPPoE terminator?
The problem is EoMPLS is point to point technology.
But PPPoE terminator is in a center of virtual star.
